SEEGIFIGATION forming part of Letters Patent No. 722,761, dated March 17, 1903. Application filed. August 7,1902. Serial No. 118,76 7. (No mcdeli To aZl whom it may concern:

Be itknowu that I, GUSTAV A. ScHonLLEs, a subject of the Emperor of Germeny, and a resident of 2 Gust-svstra-sse, Miilheim-ou-the- 5 Ruhr, Germany, have invented certain new and useful Improvements in Sighting Attachments for Guns, of which the following is a. specification.

This invention relates to gun attachments, I0 and especially to attachments for ships guns and sea-coast guns. In such attachments several slides or slide-pieces (at least two) are employed for making the several corrections in the traverse. For enamels, in a twoi 5 slide attachment one slide (the sighting-slide) carries the rear sight, while the other slide carries a scale for corrections in traversing, resulting from movement of the target, while on the head of the attachment is a fixed scale co provided for corrections in training, to be made with respect to lateral aberrations of the shot. The indexes belonging to the respective scales are mounted upon the sightslide and on the second slid'epiece. In attschmeuts heretofore known the first slidepicce (the sight-slide) is movable on the sec- 0nd, and the letteriemovahle on the head of the attachment, and the adjustment of 'the sight-slide alone, esalso the adjustment of this sight'slide together with the second slidepiece, is efiected by means of e special edjusting-screw for each.

The object of this invention is to enable both the adjustment of the sight-slide clone, 5 'a-s well as the adjustment of uaid'sight-slide and second slide together, to be accomplished by one'and the same adjusting-screw. This object is accomplished, according to the present invention, by having both slide-pieces o slidshle upon theattechrneethead independently of esch'cther and providing couplings through which the second slide-piece may be connected eitherwith the first siidepiece or with the head of the attachment. 5 An illustration of this invention is shown in the accompanying drawings, in which- Figure 1 is an elevation. Fig. 2 is a section on the line 2 2, Fig. 1, looking from the left; and Fig. 3 is a. deteilviewh u go The attachment-rod A sv provided with 'e head a, designed forthe reception of sightlug-slide B. The sight-slide B carries a notch or spider-lines or the like of known construction and is pro vided on its under sliding face i with a. nut 37 of dovetailed section, which irev- 5'5 els'in a correspondingly-fornied longitudinal groove G oi the'heed of the attachment-rod. Engaging with the ihresd of this out Z) is a screw-spindle D, which is rotatable, but not longitudinally movable, in the a.ttechment-' head. One end of the spindle D is provided with e turning heed F. On the head a of the attachment-rod is secured it track G, formed with a longitudinal slot J. Between the track- G and the-plete-lilze extension Z) of the sightslide 33, lying: parallel to the side face of the attachment-head, is arranged e slide-piece Iii, which has c section formed by two straight; portions connected by an offset and is guided upon the outer under-face of the extension b and the upper inner face of the track G. idly connecteQ with thesiide-pieee K is e screwoolt L, which extends through slot 5 of the track Gr. Upon this screw-bolt Lies fitted a nut M; constructed in the form of etoothed 7 wheel, upon which is fixed a gripwheel S through the medium of escrow s. The screwbolt L is provided with a. right-handed thread so that by turning the grip-wheel S in the direction of the hands of a. clockthe slidepiece K and the track G are pressed together through the medium oi the nut M, and can thus be coupled by friction. The teeth moi the nut M are in mesh witha. gear-wheel N, in the nave 'n of which a, screw-bolt G is se- ,3 cured against rotation and axial movement through the medium ofxan angular portion P on said screw and a, not Q. .The'screwholt 0 is provided with a left-handed thread, extends through the longitudinal slot R of the extension I), end extende'in driving connection with the internal thread of the-slidepiece Kn On the free end of the screw-holt O a. head ois'provided, which by a. turning oi the screwdoclt .0 in the direction or the 5 hands s, clock imping the fees of the ext-sh ice em By c in i-Jicn t e screw-helipresses the the extension I) the sights slide-piece K is coupled with ii slide by friction. The opgoosed glosiiion oi the screw-bolts O sud L so when the coupling between the sight-slide B and the slide-piece K is released said coupling is efiected between the track G and said slidepiece K, and vice versa.

The track G carries a scale g, whose pointer g is arranged upon the slide-piece K. Above these marks and also-upon the slide-piece K is a second scale 70, whose pointer k is located upon the sight-slide. The scale g, with the pointer 9, serves in the illustration under discussion for establishing corrections in the horizontal training necessitated by lateral aberrations of the shot, while upon the scale v wit, S (lateral aberration) and M, (range.)'

The arrow points to mark S (shownin dotted lines) when the slide-piece K is coupled with the eightslide B-that is to say, the scale it is fixed relatively to its pointer 7c'while the point of this arrow U indicates the mark M (shown in full lines) when the slide-piece K is coupled with the track G-that is to say, the scale g is in fixed relation to its pointer g.

The manipulation and mode of operation of the described arrangement are as follows: It is assumed that the several parts of the attachment are in the position shown in the drawings. The two pointers g and 70 stand at thezerdpoints in relation to their respective scales, Fig. l, and the arrow points to the mark M, Fig. 3 --that is to say, the slidepiece K is coupled with the track G by the parts I. M, while the coupling K O o is released, 2. It is now desired to establish corrections in the horizontal training due to the lateral aberration of the shot. This adjustment is accomplished by shifting the pointer g along the scale g, and is only possible when slide-piece K is coupled with the sight-slide b and uncoupled from the track G. This is attained by turning the gripwh'eel S in a direction opposite to the movemerit of the hands of a clock until the arrow indicates the mark S. By this movement the nut M of the spindle L is released. Simultaneously the screw 0 will be turned, through the medium of the teeth'm and the toothed wheel N, in the direction of the hands of a clock, so that the coupling between the slidepiece K and the sight-slide B is established. it nowtho adjusting-screwD is turned through the medium of the grip-wheel F, it follows that the sight-slide B, together with the slidepiece K, will move along the track G, so that the corrections of the horizontal training required by lateral aberrations of the shot are established through the medium of the pointer 1', carried by the slide-pieceK, in connection with scale 9. N e must now establish corrections in the horizontal training necessitated by wind or specific velocity or by the velocity of the target through the medium'of the scale and its pointer 70 without "altering the adjustment that has already been established. For this purpose the scale g must be coupled immovably with relation to its pointer 9, while the coupling of the scale 70 to its pointer is must be released. Thisis accomplished by shifting the arrow U, Fig. 3, upon the mark M. .By this means the nut M turns in the direction of the hands of a clock, the screw 0 turning'in the opposite direction, so that the slide-piece K is coupled with the track G, While the coupling of the slide-piece with the sight-slide B is released. By throwing the adjusting-screw D now it is obvious that the sight-slide B moves relatively to the slidepiece K, which remains at rest with the track G, so that the corrections in the horizontal training necessitated by the wind, 850., may be indicated by the pointer k on the scale 7c.

It is obvious without further discussion that each of the two adjustments can be madeiudependently of the other by the coupling or uncoupling of the appropriate parts-that is to say, by oscillating the arrow-U between the marks L and M-and that the details may be varied without departing from the spirit of the invention.
